摘要
本文对三年华北落叶松 (Larisprincipis-rupprechtiiMayr)幼苗各部位酶活性和含水率的变化规律进行研究 ,结果表明 :(1)各部位间的多酚氧化酶 (PPO)存在较显著的差异 ;(2 )铜元素与PPO的关系较为密切 ,锌元素对超氧化物歧化酶 (SOD)活性作用较显著 。
This article researches on enzymes activities in different positions and changing pattern of moisture contents in seedling three-year-old \%Larix principis-rupprechtii\%. The results show that there exist apparent differences of polyphenol oxidase(PPO) in different positions.Copper has close interaction with polyphenol oxidase.Zinc has a relatively drastic effect on superoxide dismutase(SOD),and plays an important role in stability of cell membrane.
